informix - 坏主块'/dev/chunk1317'？
问题描述
通过操作系统级克隆将informix二进制文件迁移到新服务器后，当我执行 oninit -vy 时出现警告，就像无法打开某些块一样。然后我要求系统管理员链接那些丢失的块并再次执行 oninit -vy 再次提示警告并指出这些块是坏块。这背后的原因是什么。当块重新配置到新服务器时是否发生任何错误

这是这些块的 onstat -d 输出

解决方案
我可以通过以下命令打开这些块来解决上述错误。
onspaces -s [dbspace_name] -p [pathname] -o [offset] -O
例如：-
onspaces -s dbspace1 -p /dev/chunk1186 -o 96 -O
